2. Crop King Seeds – A Reliable Canadian Seed Bank that Ships to the US
- Free delivery on $300+ orders
- 80 percent germination rate
- “Five crown” ranking system
- Germination guide for new growers
- Simple e-commerce layout
- Useful infographics regarding genetics and THC-CBD ratios.
- $10 regular delivery fee on orders under $300
- Regular shipping is slow (7 to 14 business days)
- Website seems aimed at beginners
This US seller’s site offers a nice simple layout with many large sections featuring choices like auto flower, feminized, and high-CBD, as well as regular weed seed types, which gives you a fair amount of choices. One thing that’s especially helpful is their “Germination” section. It provides step-by-step directions on how you can guarantee that 80 percent of the seeds from them will end up reaching germination. That seems a bit low when you compare it to some other seed banks, but perhaps Crop King is just being realistic.
One of the best things about this company is the “five-crown” rating system. It’s quite similar to a “five-star” rating system and is controlled by a variety of user reviews that are unbiased, making it an excellent way for trying new strains with recommendations from other Crop King customers.
The Crop King website offers a rather generic e-commerce layout but you have the ability of filtering through all of their seeds by genetics and type, as well as CBD and THC percentages. Shipping’s also free when you order $300 worth of seeds or more. Regular shipping runs $10 and arrival takes 7 to 14 business days. Express shipping runs $30, which is a bit expensive but let’s move on to the pros and cons of Crop King Seeds:
3. Marijuana Seeds NL (MSNL) – Best for Discreet Shipping
- Offers Stealth Shipping – a very discreet shipping method where the weed seeds are hidden within some other objects, like DVD cases, prior to shipping.
- 15 percent off bitcoin orders
- Long Standing since 1999
- Fun quiz for helping you pick the best seeds
- Award winners of High Times Cup and Cannabis Cup
- Variety of shipping options (includes stealth shipping)
- FREE seeds with all orders for trying new strains
- Wide range of seeds
- International shipping may take weeks
- No free delivery unless buying in bulk
- US delivery costs more
- Confusing charts for describing seed strains
This is a cannabis seed bank that is based in the Netherlands and has been in business since 1999. With more than 20 years of experience in the sale of high-quality seeds, they have numerous options for auto flowering, feminized, indoor and outdoor, regular, high-CBD seeds, and much more.
One fun thing about their website is the quiz that asks “What marijuana strain are you?”. It helps customers to discover the MSNL seeds based upon specific growing conditions, weed preference, and what you’re expecting from the finished buds. At the end, you’ll have four weed seed options chosen for fitting with your climate, growing skills, and personality. This feature is nice for newbie growers.
MSNL states that their seeds have a 90 percent germination rate, which is more refreshing and honest than promising a 100 percent germination rate like some other seed banks may do. And, all of the seeds are hand-checked by their expert staff with plenty of experience in marijuana seeds from Amsterdam, therefore you’re assured a top product. And, they stock some major named strains, including some High Times Cup and Cannabis Cup and award-winners, like Buddha, Grandaddy Purps, Northern Lights, and White Widow. You also get FREE seeds with each order, which is a great way for you to try some new seeds while also helping the new seed strains with acquiring the much-needed attention in an extremely busy market.
Standard delivery is currently around $6.25 but if you buy in bulk, you get free delivery. Their deliveries generally arrive in the US in approximately 6 to 12 days, but sometimes end up taking a few weeks. Multiple payment methods are available, including cash, credit/debit cards, checks, bank wires, or bitcoin. Buying with bitcoin gets you a 15 percent discount. Here are the basic pros and cons:
4. Seedsman – Best Breeders’ Seed Bank
- 15 percent bitcoin discount
- A regular customers’ loyalty points system
- A-Z breeders’ list
- Free seeds included in every order
- Plenty of seed types in-stock
- Tons of accessories from hemp bags and informational books to storage jars
- User reviews for helping you decide
- Cheesy-feeling ads on their website’s front page
- Steep insurance and delivery charges
- User reviews that feel a bit biased
This is one of the most widely trusted cannabis seed banks shipping to the US. It’s also seriously geared toward growers with considerable experience. In fact, the company hosts an annual “Photo Cup” competition aimed at encouraging growers to submit photos of their own weed crops, preferably complete with a creative, fun, or just plain impressive twist of some kind.
The best thing about this cannabis seed seller is its massive variety of licensed breeders. In fact, they even provide a very long alphabetical list of all the seeds they stock and their breeders. If you’re searching for a specific big-name or even a niche breeder, you’re likely to find them and their weed seeds stocked by Seedsman.
In addition, you can also find all of the usual selections of feminized/autoflowering/ seeds along with entire sections containing popular strain variations, including Northern Lights, Sour Diesel, Skunk, Cheese, and the ever-popular White Widow.
Seedsman proudly stocks plenty of award-winning seeds plus some very specific categories tailored to specific growing locations. For example, you can purchase fast-flowering strains, mold-resistant strains, and even seeds suitable for growing at high altitudes, like in Colorado.
Every product listing contains a review at the bottom of the page and, with each purchase, you’ll be receiving some free seeds along with loyalty points for buying. And, when you’re buying and paying with bitcoin, you’ll also be getting 15 percent off. If that isn’t enough, you’ll also receive 25 percent more off for your first time paying with bitcoin! There’s only one downside and that is rather pricey delivery add-on charges, like the delivery insurance fee ($9.04) and the delivery charge ($8.98). At this point, let me give you the basic pros and cons of Seedsman:
5. Quebec Cannabis Seeds (QCS) – Fastest Shipping
- Credit card charges are under a non-obvious company name
- 20 percent Bitcoin payment discount
- More than 15 years of seed bank experience,-Stealth shipping
- A variety of autoflower, regular, CBD, feminized, and mixed seeds
- US customers can pay in USD
- 3.8 percent credit card payment fee
- Minimum $70 order amount
- Only one $10 standard shipping option
- Website is a bit less sophisticated than some others
QCS has a website that was specially designed for people with prior experience in cannabis seed growing, (at least that’s the impression you get). Their website has been up-and-running for 15 years or more now, however, the fact is that QCS has been supplying all of Canada (and even the rest of the world) with some pretty high-quality seeds for almost 20 years. There are a number of different types and strains available, including high-CBD, autoflowers, mixed packs, and feminized, as well as outdoor, regular, and even some limited edition seeds. You can also submit a request for in-depth info about any other strains that you’re interested in. You’ll receive it in a format much like eBay product descriptions complete with bullet points. This may not be the world’s most sophisticated online cannabis seed bank but it’ll do the job if you know what you’re actually looking for. And, for all deliveries, they use very discreet stealth shipping. The only problem is that but they only offer a vague delivery window for the ETA of the product shipment.
US customers are charged in USD, so you don’t have to deal with Canadian dollar conversion. You can also pay in a number of ways, however, it’s important to know that any credit card payment accrues a 3.8 percent fee. And, if you pay with Bitcoin, you’ll get a 20 percent discount on your entire order. So, let’s move on to the pros and cons to give you a quick picture of this seller:
Is buying marijuana seeds online and having them shipped to the US safe?
Although you might think that it’s risky to order cannabis seeds online and receive them in the mail, the truth is that there’s minimal risk involved even when placing an order with a seed bank overseas. Don’t worry about customs laws either. Some people think that, if their seeds are intercepted, they’ll end up on a list and somebody will come knocking on their door (kind of like in the movies).
The more likely scenario would be that your seeds wouldn’t even be found. If they were, customs would probably just throw them out and then proceed by sending you a very official-looking letter that simply says that they were confiscated. And, that would be that.
However, if you’re having seeds shipped from a foreign country to the US and worry about the possibility of interception, many of the best seed banks online are offering what is called “stealth shipping”. This is basically just a very discreet shipping method where the weed seeds are hidden within some other objects, like DVD cases, prior to shipping. This can help keep your package from being flagged as suspicious.
While we’re on the subject of shipping, don’t request expedited delivery or any delivery requiring a signature. Why? Well, you don’t want to intentionally draw attention to the package or have to sign for a cannabis seeds delivery. That’s a bit of a no-brainer. Also, when ordering in large amounts, multiple smaller orders from a variety of vendors will spread your risk along the lines of that old saying “Don’t put all of your eggs in one basket”.
Seed Bank Payment Options
Another consideration is the payment option you choose and how it’ll be charged. If your goal is to stay way under the radar, you might find that bitcoin is the most encrypted currency form plus it’s virtually untraceable. Numerous top cannabis seed banks are actually offering a discount if you’re paying in bitcoin. Alternatively, you can pay via credit card since credit card purchases are insured and better protected in case something goes awry.
If you want the best seed bank possible I’d definitely recommend ILGM. However all sites on this list have been thoroughly vetted and will deliver a good seed shopping experience.
I’m hoping that this buying guide gives you a little guidance and helps you with finding the seed seller that’s just right for you and your needs. And, last but not least, happy growing!

Cannabis seeds 101: How to grow marijuana from seed
Cannabis is grown from one of two sources: a seed or a clone. Seeds carry genetic information from two parent plants and can express many different combinations of traits: some from the mother, some from the father, and some traits from both.
In commercial cannabis production, generally, growers will plant many seeds of one strain and choose the best plant. They will then take clones from that individual plant, which allows for consistent genetics for mass production.
If cannabis is legal in your state, you can buy seeds or clones from a local dispensary, or online through various seed banks.
Cannabis seeds vs. clones
For the typical homegrower, it may be easier to obtain cannabis seeds rather than clones. Growing from seed can produce a stronger plant with more solid genetics.
Plants grown from seed can be more hearty as young plants when compared to clones, mainly because seeds have a strong taproot. You can plant seeds directly into an outdoor garden in early spring, even in cool, wet climates.
If growing outside, some growers prefer to germinate seeds inside because they are delicate in the beginning stages of growth. Indoors, you can give weed seedlings supplemental light to help them along, and then transplant them outside when big enough.
Most seeds that you will buy are regular seeds as described above, but here are a couple more types.
How weed seeds work
Cannabis can be either male or female—also called “dioecious”—but only females produce the buds we all know and love. For reproduction, males have pollen sacs and pollinate females, causing female flowers to produce seeds.
Once cannabis seeds are mature, the female plant begins to die, and seeds are either dropped to the ground where they grow into new cannabis plants next spring, or the seeds are harvested for processing into seed oil or food products, or stored so they can be sown in the ground later and become the next generation of plants.
To get the buds found in medical and recreational stores, female cannabis plants are grown in an environment without males—or the males are removed from the area before they release pollen—so the females don’t create seeds. Females can then focus their energies on producing buds and not seeds—this high-potency marijuana is traditionally known as “sinsemilla,” meaning “seedless.”
Some varieties of cannabis can produce male parts alongside female flowers on the same plant, especially if exposed to environmental stressors. These plants are known as hermaphrodites, and sometimes they can self-pollinate to create seeds.
Pros and cons of using cannabis seeds
Check out Johanna’s full video series on how to grow weed on Leafly’s YouTube .
If buying from a reputable breeder or seed bank, growing from seed is the best way to ensure your plants will have solid genetics and start clean, meaning they won’t come with diseases or pests.
Also, buying from a reputable breeder or seed bank will give you a sense of what a particular strain will look and smell like, how it will grow, and how much it will yield at harvest.
The main drawback to growing from seed is there is no guarantee as to what you’ll end up with—if you buy a regular pack of cannabis seeds, it will be a mix of males and females. You’ll need to sex them out (more below) to identify the males and get rid of them, because you don’t want your females producing seeds.
Sexing marijuana plants can be a time-consuming process, and if you don’t catch males, there is a risk that even one males can pollinate your entire crop, causing all of your female weed plants to produce seeds.
One way to avoid sexing plants is to buy feminized seeds (more below), which ensures every seed you plant will be a bud-producing female.
You can also minimize headaches and avoid the hassle of seed germination and sexing plants by starting with clones.
How weed clones work
Aside from producing cannabis through seeds, or sexual reproduction, you can also reproduce the plant through cloning, or asexual reproduction. A clone is a cutting that is genetically identical to the plant it was taken from—that plant is known as the “mother.”
Pros and cons of using cannabis clones
Through cloning, you can create a new harvest with exact replicas of your favorite plant. Because genetics are identical, a clone will give you a plant with the same characteristics as the mother, such as flavor, cannabinoid profile, yield, grow time, etc. So if you come across a specific strain or phenotype you really like, you might want to clone it to reproduce more buds that have the same effects and characteristics.
With cloning, you don’t have to get new seeds every time you want to grow another plant—you just take a cutting of the old plant—and you don’t have to germinate seeds or sex them out and get rid of the males.
One drawback of clones is they need to be taken during the vegetative stage of a plant—flower is too late—so if you have a small setup with only one light, it can be hard to keep clones alive while flowering other plants, because the two need different amounts of light.
Another drawback to clones is they can take on negative traits from the mother plant as well. If the mother has a disease, attracts pests, or grows weak branches, its clones will probably have the same issues.
Additionally, every long-time grower will tell you that clones degrade over time.
What are feminized cannabis seeds?
Feminized cannabis seeds will produce only female plants for getting buds, so there is no need to remove males or worry about female plants getting pollinated. Feminized seeds are produced by causing the monoecious condition in a female cannabis plant—the resulting seeds are nearly identical to the self-pollinated female parent, as only one set of genes is present.
This is sometimes referred to as “cloning by seed” and will not produce any male plants. This is achieved through several methods:
- By spraying the plant with a solution of colloidal silver, a liquid containing tiny particles of silver
- Through a method known as rodelization, in which a female plant pushed past maturity can pollinate another female
- Spraying seeds with gibberellic acid, a hormone that triggers germination (this is much less common)
Most experienced or commercial growers will not use feminized seeds because they only contain one set of genes, and these should never be used for breeding purposes. However, a lot of beginning growers start with feminized seeds because they eliminate the worry of having to deal with male plants.
Top feminized cannabis strain families
A lot of classic weed strains that have been around for a while come in feminized form. Some popular fem seeds are:
- OG Kush
- GSC (Cookies)
What are autoflowering cannabis seeds?
Autoflowering seeds are also popular with beginning growers. They are easy to grow because you don’t have to worry about light cycles and how much light a plant receives.
Most cannabis plants begin flowering when the amount of light they receive on a daily basis reduces. Outdoors, this happens when the sun starts setting earlier in the day as the season turns from summer to autumn. Indoor growers can control when a plant flowers by reducing the daily amount of light plants receive from 18 hours to 12 hours.
However, a type of cannabis called Cannabis ruderalis, which developed in extreme northern conditions without much sunlight, will begin flowering once the plant reaches a certain age—they automatically start flowering regardless of the amount of light they receive, hence the name “autoflower.”
Pros and cons of growing autoflower
Because they grow and flower quicker, growers can fit in multiple autoflower cannabis harvests into the span of one regular harvest.
Autoflowers can be started in early spring and will flower during the longest days of summer, taking advantage of high quality light to get bigger yields. Or, if you get a late start in the growing season, you can start autoflowers in May or June and harvest in the fall.
Also, autoflower plants are small—perfect for closet grows or any small grow, or growing outdoors where you don’t want your neighbors to see what you’re up to.
A couple big drawbacks, though: Autoflower strains are known for being less potent. Also, because they are small in stature, they usually don’t produce big yields.
However, potency in autoflowering varieties has increased significantly since their initial introduction, with some breeders crossbreeding the low-THC ruderalis with other more potent varieties.
Tips for growing autoflower marijuana seeds
Autoflowering strains require some preparation, as they will grow quickly and start to flower whether or not you’re ready for them.
Many marijuana growers start autoflowers early in the season, and at a different time than a regular crop, so keep the season and climate in mind when growing and harvesting—your plants still need warmth to grow, and rain can give them bud rot. Consider growing in a greenhouse to protect them.
Because training happens during vegetative growth, for autoflowering plants, this period could be as short as a few weeks, which means time is limited. Try topping your autoflowers after they have three nodes, and stop once they begin to flower. You will want to prune them lightly.
Go easy on nutrients
Autoflowers don’t need lots of nutrients because they’re small and don’t spend much time in the vegetative cycle. They won’t need as much veg nutrients—such as nitrogen—but will need more bloom nutrients.
What are high-CBD cannabis seeds?
CBD, or cannabidiol, is one of the chemical components—known collectively as cannabinoids—found in the cannabis plant. Over the years, humans have selected plants for high-THC content, making cannabis with high levels of CBD rare. The genetic pathways through which THC is synthesized by the plant are different than those for CBD production.
Cannabis used for hemp production has been selected for other traits, including a low THC content, so as to comply with the 2018 Farm Bill. Consequently, many varieties of hemp produce significant quantities of CBD.
As interest in CBD as a medicine has grown, many breeders have crossed high-CBD hemp with cannabis. These strains have little or no THC, 1:1 ratios of THC and CBD, or some have a high-THC content along with significant amounts of CBD (3% or more).
Seeds for these varieties are now widely available online and through dispensaries. It should be noted, however, that any plant grown from these seeds is not guaranteed to produce high levels of CBD, as it takes many years to create a seed line that produces consistent results. A grower looking to produce cannabis with a certain THC to CBD ratio will need to grow from a tested and proven clone or seed.
How to germinate marijuana seeds
Germination is the process in which a seed sprouts and begins to grow into a new plant. Also referred to as “popping,” germination is the very first step in starting your weed grow.
Marijuana seeds can be acquired from an array of sources and can vary in quality. For more info on how to buy marijuana seeds, check out our Guide to buying cannabis seeds.
Cannabis seeds require three things to germinate: water, heat, and air. There are many methods to germinate seeds, but for the most common and simplest method, you will need:
- Two clean plates
- Four paper towels
- Distilled water
Take four sheets of paper towels and soak them with distilled water. The towels should be soaked but shouldn’t have excess water running off.
Take two of the paper towels and place them on a plate. Then, place the marijuana seeds at least an inch apart from each other and cover them with the remaining two water-soaked paper towels.
To create a dark, protected space, take another plate and flip it over to cover the seeds, like a dome.
Make sure the area the seeds are in is warm, somewhere between 70-85°F.
After completing these steps, it’s time to wait. Check the paper towels once a day to make sure they’re still saturated, and if they are losing moisture, apply more water to keep the seeds happy.
Some seeds germinate very rapidly while others can take a while, but generally, seeds should germinate in 3-10 days. If it’s been two weeks and a seed hasn’t sprouted, it’s probably a dud and won’t sprout.
A seed has germinated once the seed splits and a single sprout appears. The sprout is the taproot, which will become the main stem of the plant, and seeing it is a sign of successful germination.
It’s important to keep the delicate seed sterile, so don’t touch the seed or taproot as it begins to split.
Transplanting germinated cannabis seeds
Once you see the taproot, it’s time to transfer your germinated seed into its growing medium, such as soil.
- Fill a 4-inch or one-gallon pot with loose, airy potting soil
- Water the soil before you put the seed in; it should be wet but not drenched
- Poke a hole in the soil with a pen or pencil—the rule of thumb is: make the hole twice as deep as the seed is wide
- Using a pair of tweezers, gently place the seed in the hole with the taproot facing down
- Lightly cover it with soil
Keep a close eye on the temperature and moisture level of the soil to keep the seed happy. It’s very delicate at this stage. Use a spray bottle to water it—over-watering can suffocate and kill the delicate sprout.
Within a week or so you should see a seedling begin to grow from the soil.
Germinating cannabis seeds doesn’t always go as planned. Some seeds will be duds. Others will be slow and take longer to sprout. But some will pop quickly and grow rapidly.
This is the beauty of seeds—often, you can tell which plants or genetics will thrive right from the get-go. This will help you determine which plants you want to take cuttings from for clones or for breeding if you want to create a seed bank of your own.
How to sex a pot plant
Check out Johanna’s full video series on how to grow weed on Leafly’s YouTube .
As we’ve mentioned, cannabis is a dioecious plant, meaning male and female reproductive organs appear on different plants.
Because only female cannabis plants produce buds and you want them to focus all their energy on producing buds and not seeds, it’s important to identify and get rid of male weed plants so they don’t pollinate females. If females are pollinated, it will give you buds filled with seeds, making your weed harsh and unpleasant.
Cultivating males is important for breeders trying to cross new strains and genetics, but most people growing for buds will want to remove the males.
As mentioned above, you can skip the processing of sexing weed plants by growing with feminized seeds or clones.
If growing male and female cannabis seeds, they’ll start to show their sex organs, or “pre-flowers,” after 8-10 weeks from germination.
Cannabis plant sex organs appear on nodes, the points where branches grow off from the main stalk.
Males will have round balls—these will develop into pollen sacs, which will release pollen into the air when mature.
Females will have a round structure with long hairs—these hairs will develop into pistils, which will catch pollen in the air.
Pre-flowers can initially be extremely small and hard to identify with the naked eye, but you can use a magnifying glass to get a better look.
Can I grow a seed I found in a bag of weed?
Finding a cannabis seed in your stash is not ideal, but we’ve all been there before. Although much less common than it once was, it still happens. Sometimes you’ll notice one when grinding down some flower, or you’ll see one pop, spark, and crackle from the heat of a lit bowl.
These are referred to as “bagseeds” and whether or not you can grow one will depend on where it came from.
Is a bagseed good or bad?
Seeds found in finished cannabis buds can develop for a number of reasons. For example, a male plant may have accidentally pollinated a flowering female during the growing process. But more commonly, they’re a sign of stress and can be attributed to high temperatures during the final stages of flowering or an exaggerated spike in climate or environment.
Seeds can also form in plants with genetic disorders or instability, like hermaphrodites—plants that develop both male and female reproductive parts. Generally, stress and genetic disorders are viewed as bad, so temper expectations with any plant you start from a bagseed.
But sometimes you get lucky and find a mature seed in some really nice herb. Strains like the legendary Chemdog wouldn’t be possible without adventurous smokers planting and proliferating the seeds they found in a bag of kind bud.
So don’t discount bud because it has a seed or two in it. While not ideal, it could be the origins of the next great weed strain.
Ask yourself a few questions to decide if it’s worth the time and energy to grow the seed.
Was the seed found in good weed?
If you don’t like the flavor, effects, or even the look of the bud, then it’s probably not worth growing.
Are you ready to grow?
Growing marijuana takes a certain level of commitment: time, energy, and financial resources, so be sure you can commit to the whole process.
Is the seed viable?
For a seed to be viable, it must be mature enough to have a completely formed genetic blueprint, and it must be strong enough to germinate and pop through its hard casing and sprout its crucial taproot.
There are a few indicators that will give you a sense of whether the seed is worth germinating.
- Tiger stripes—dark stripes on the seed which resemble veins on a leaf are generally good
- Solid shell—a seed should be able to withstand a little pressure when pinched between your fingers; if it crumbles or cracks, it’s no good
Immature seeds tend to be light in color and have a soft outer shell.
In some cases, even if a seed isn’t completely mature, there’s still a chance it could be viable. But often these are extremely weak, take long to develop, and express other unfavorable characteristics. Growers usually discard weak plants to free up space.
You might also find a mature seed that has been physically damaged through poor handling, like rough trimming. In those cases, it probably isn’t worth the effort to try and germinate the seed.
But if the seed you found looks decent, you might as well germinate it and see what sprouts.
Time to germinate
Viable or not, there’s only one sure way to find out if a bagseed will grow. If you’re simply curious to learn and not as concerned with the overall outcome, you can plant a couple of bagseeds outside and see what happens.
If you’re ready for a more serious approach, make sure you have the space for a proper garden and pop the seeds to see what fruit they bear.
Even if your seed sprouts fast and grows vigorously, it still has roughly a 50/50 chance of being female and producing buds, instead of turning out to be a male.
Remember, once a seed germinates, the real work begins. Sexing, selecting, vegetative growth, flowering, and the eventual harvest all lie ahead.
How to buy cannabis seeds
Cannabis seeds can be found on numerous online seed banks, but note that it is illegal to bring seeds into the US and Customs will seize any cannabis seeds that they find in packages or on a person. In legal and medical states, you may purchase seeds at a dispensary.
